Abstract: ABSTRACT     A retractable blade knife adapted for use selectively with either the long narrow standard type of blade having score lines for breaking off successive end portions when worn and a large hole at its rear end or the shorter wider type of blade, sometimes double ended, with one or more smaller holes.  The knife has a two part blade carrier.  One part slides longitudinally relative to the other into -two click positions.  In each of these positions the upper part can pivot at its front end relative to the lower part.  The rear end of the upper part is spring-biased away from the lower part to engage detent means on the upper part with detent means on the casing to locate the blade carrier.  The front part has two bosses of different diameters, the small diameter boss projecting above the large diameter boss.  All the blades lie in the same plane in the casing when in use respectively.  The lower blade carrier part provides two pivotal support heights for the front end of the upper blade carrier part in the two click positions.  The lower support height positions the smaller boss to engage the shorter, wider type of blade.  The upper support height positions the larger boss to engage the long narrow type of blade.

Abstract: Abstract of the Disclosure A bridge circuit, interconnected with a sample box containing a sample of particulate material, is energized by H test signal and provides a bridge output signal whose phase, relative to the phase of the test signal, and whose amplitude are related to the electrical admittance of the sample. After compensation for variations in temperature and bulk density of the sample, the bridge output signal is applied to a first controlled rectifier which is also provided with a reference signal whose frequency is identical to that of the test signal and whose phase is shifted by a predetermined amount from that of the test signal. The first controlled rectifier passes only that component of the bridge output signal in-phase with the test signal to provide a first DC signal related to the measured conductivity of the sample. The bridge output signal is also applied to a second controlled rectifier which is also provided with the reference signal, as coupled through a 90? phase shift circuit. The second controlled rectifier passes only that component of the bridge output signal which is 90? out-of-phase with that of the test signal to provide a second DC signal related to the measured dielectric coefficient of the sample. In order to obtain a signal which is related to the moisture content of the sample, the first DC signal is applied to one input of a differential amplifier whose other input is provided with a threshold signal representing a predetermined conductivity value. When the measured conductivity exceeds the predetermined value, the differential amplifier provides an output signal equal to the difference between the measured conductivity and the predetermined value. This output signal is modified by a signal shaper into a signal representing a corresponding percentage. A multiplier circuit multiplies the second DC signal by the percentage represented by the output signal from the signal shaper to obtain a moisture correction signal which is subtracted from the second DC signal to obtain an output signal related to measured moisture content. An alarm indication is also provided when the measured conductivity goes above a value representing an excess conductivity condition in the sample.

Abstract: ELECTRICAL CONNECTOR     ABSTRACT OF THE DISCLOSURE        A high temperature hermetic electrical connector is disclosed in which socket contacts are hermetically sealed in a rear insulator of one connector member.  A "napkin" spring is mounted on a forward portion of the body of each socket con-tact which extends forwardly of the rear insulator.  A front insulator is removably mounted on the front face of the rear insulator, and serves to retain the "napkin" springs on the socket contact bodies.  When the front insulator is removed, a damaged "napkin" spring may be replaced in the field by a new spring without affecting the sealing integrity of the connector. In a second embodiment, a metal hood slidably mounted on a contact body removably retains the "napkin" spring thereon.

The distributor comprising a base portion and a cap portion formed of like insulative material.  The base and cap portions of the distributor contain separate sets of switching contacts connected to associated external terminals and separate rotor conductors on a common rotor element.  Half the externally mounted terminals in each portion extend in a direction diametri-cally opposite to the other half so as to eliminate external spark plug wire crossover at the distributor and are electrically connected to the contacts by means of wires internally molded into the insulation of the portions. An installation alignment feature includes a series of apertures in the rotor and the base, whereby a pin inserted therein aligns the rotor conductors to be in accurate registration with a predetermined pair of switching contacts. A unique hexagonal drive shaft provides for an allowable degree of error in mounting the distributor with respect to an axial drive socket on the engine.

The thus produced optical wave-guide material is improved in the boundary condition of these two materials fused and therefore very low in light attenuation.

Abstract: CONTROL CIRCUITRY FOR GATED DIODE SWITCHES            Abstract:        A gated diode switch requires a voltage applied to the gate which is more positive than that of the anode or cathode in order to break current flow between the anode and cathode.  In addition, a current of at least the same order of magnitude as flows between anode and cathode must be sourced into the gate of the switch to break current flow.  The use of a second gated diode switch coupled by the cathode thereof to the gate of a gated diode switch which is to be controlled provides a high voltage and current capability circuitry for cutting off (interrupting) or inhibiting current flow through the gated diode switch.  The state of a gated diode switch is thus controlled by a second gated diode switch.  The state of the second gated diode switch is controlled by a voltage control circuit having only relatively modest current handling capability.

Abstract: VALVE OPERATOR            Abstract:    A fail-safe-open actuator for actuating valves and the like which comprises a pair of opposed cylinders (16,1&) joined to define piston chambers (20,22), the axes of which are generally perpendicular to a valve stem.  Pistons (24,26) in the cylinders are connected to the valve stem (40) by toggle links (54,56), the pistons being resiliently urged toward the ends of the assembly which corresponds to an open-valve position. To close the valve, a pressurized fluid, such as air, is introduced into the piston chambers and to the pistons at sufficient pressure to counter the resilient means (28,30) so as to move the pistons away from their rest, valve-open positions, and thus move the valve stem perpendicularly to the axis of the piston chamber. A handwheel (94) is provided to manually close the valve by moving the pistons from their rest positions.          A solenoid controlled pneumatic valve (74) may be used to control the supply of pressurized fluid, such as air, to the actuator.  Either a failure in fluid pressure or an electrical failure will result in the pistons being urged to the rest positions and also result in opening the connected valve, i.e., the failure mode.

Filed: 1980-06-18
Granted: 1982-11-02
Abstract: ABSTRACT A multispectrum light detection system for controlling exposure time of a photoresist coated substrate in a projection aligner-printer machine wherein the relatively narrow spectral responsivity characteristics of a selected photoresist is matched to the wider spectrum inherent in the output flux of a combined light source and optical system. A representative sample of the system's wide spectrum output flux is divided into three or more narrower spectral bands each of which is measured by its own detector that provides an electrical signal proportional to the radiant flux intensity within that band. The resultant electrical signals from the separate spectral bands are weighted and combined in a summing amplifier to form a composite exposure control signal. Means are provided to adjust the contribution of each electrical signal to the combined control signal in accordance with known spectral response characteristics of the photoresist.
